A circular The beehive glass 21 is half an oval whenopening 12 is formed at the axial center of seen in cross section as in Fig. 2, and has a the portion of the reflector 11 and an opensmooth curved outer face 30 and the inner ing 13 is formed by cutting away the maface is rough ground to produce the steps terial so as to leave a rim 14 around the 31, 82, 33, 3A and 35 extending from the. opening 12 and cut on lines 15 and 16 in a flange 22 towards the closed end and center, plane level with the axial center of the thereby making the glass translucent, and

the lamp 27 extends into the open end of the glass.

The portions of the collar 18 cut away on the lines and 26 must be properly related to the length of the collar from the ring 23 backwardly to the reflector 1 and to the circumference or diameter of the collar. If the reflector 1 is deeper the collar 18 will be longer and the cut away portion will be longer on the lines 25 and the lines 25 will be raised to make the opening wider. 1

The beehive glass 21 is clear glass with rough ground inner surfaces and the glass 9 is plain flat clear glass. The steps 31, 32, 33, 34c and 35 are beveled or tapered from the flange 22 outwardly with flat shoulders between the steps.

Various changes maybe made without departing from the spirit of our invention as claimed.

VVe'claim: I Y V 1. A headlight comprising a concavo convex reflector having a rim on its outer edge, an opening in the axial center, and a cut away portion below the axial center adapted to form an opening for rays projected from a lamp, and a beehive glass mounted in the opening of the reflector.

2. A headlight comprising in combination a concavo convex reflector having a circular rim, an openingat its axial center, and a cut away portion below the axial center, a beehive glass mounted in the opening, and a lamp support, the lower portion of which forms a reflector mounted behind the concavo convex reflector.

3. A headlight comprising in combination a concavo convex reflector having a circular rim, an opening at its axial center and a cut away portion below the opening, a beehive glass mounted in the opening, a lamp support having a lamp mounted behind the concavo convex reflector, and having a reflecting surface at its lower portion adapted to reflect the rays from the lamp through the said cut away portion.

vex portion, a collar mounted in the opening and extending backwardly and having a lower portion cut away, a beehive glass mounted in the forward end of the collar, the material of the 'concavo convex portion being cut away to leave a rim around the lower part of the collar and to form an opening for the projection rays, a reflector behind the collar, a lamp socket extending through the reflector, and a lamp in the lamp socket in the forward end of the collar and extending into the beehive glass.

In'testimony whereof we have signed our names to this specification.
